I didn't have any problem with copypasting password.
Btw there's usefull little downloading program called wget.exe (known from linux world).

You can basicly dl all the rar files from command prompt with this command:
wget -r -l2 -np -nc -A.rar http://www.benchzone.com/Downloads/Temp/

Or you can use DownThemAll! in Firefox and goto the folder and right click and select downthemall and select only the RAR files and hit start
